Detailed Description

A GdkVisual C++ wrapper interface.

Provides Visual, an object that describes a particular video hardware display format.

Enumeration Type Documentation

enum VisualType

A set of values that describe the manner in which the pixel values for a visual are converted into RGB values for display.

Enumeration values:

VISUAL_STATIC_GRAY Each pixel value indexes a grayscale value directly.

VISUAL_GRAYSCALE Each pixel is an index into a color map that maps pixel values into grayscale values (the color map can be changed by an application).

VISUAL_STATIC_COLOR Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values.

VISUAL_PSUEDO_COLOR Each pixel is an index into a color map that maps pixel values into rgb values (the color map can be changed by an application).

VISUAL_TRUE_COLOR Each pixel value directly contains red, green, and blue components (The red_mask, green_mask, and blue_mask fields of the GdkVisual structure describe how the components are assembled into a pixel value).

VISUAL_DIRECT_COLOR Each pixel value contains red, green, and blue components as for GDK_TRUE_COLOR, but the components are mapped via a color table into the final output table instead of being converted directly.
